Someone sent you a .webp and nothing on your computer will open it. This tool turns WebP images into ordinary JPG files right here in your browser — one file, or a whole folder in one go. Nothing gets uploaded, there is no signup, and the JPG saves straight to your device.

WebP is a Google image format from 2010, built specifically for the web. Every current browser shows it happily, which is why so many sites serve it, and why a right-click "save image as" keeps handing you a file ending in .webp.
WebP is one format doing two jobs: photographs smaller than JPG, and transparency like PNG. That combination is why the web took to it — and why software written before it existed has never heard of it.
The trouble starts the moment you leave the browser. Photoshop only added native WebP support in version 23.2, back in February 2022. Older Windows Photo Viewer will not touch it. Neither will a lot of print shops, older versions of Office, some email clients, and a long tail of professional software written before the format existed. So a file that looks perfect on a web page becomes useless the second it needs to go somewhere else.
Converting to JPG fixes that for good, and the only cost is a slightly bigger file — JPG has been readable by more or less everything since 1992. One thing to watch: JPG cannot store transparency. If your WebP has a transparent background, that area comes out solid white, so for a logo or a cut-out use PNG or just keep the WebP.
| WebP | JPG | |
|---|---|---|
| File size | Roughly 25–35% smaller at the same quality | Larger, but universally accepted |
| Transparency | Supported — full alpha channel | Not supported; transparent areas become white |
| Browser support | Every current browser since 2020 | Every browser ever made |
| Photoshop | Native only from version 23.2 (Feb 2022) | Supported since the beginning |
| Older software | Frequently refused | Effectively never refused |
| Best used for | Images served on a website | Files that must open anywhere |
Drop the WebP onto this page and download — the output is already set to JPG, so a straight conversion takes one step. The file is processed in your browser rather than uploaded, and saves at full resolution with no watermark and no account.
Because the program predates the format or never added support — Photoshop only gained native WebP in version 23.2, February 2022. Which software supports WebP and which does not covers it in full.
Slightly, because both formats are lossy and you are re-encoding once. At quality 85 the difference is invisible on a photograph at normal viewing size. It is a single generation of loss, not cumulative — converting once is fine, converting back and forth repeatedly is not.
It is lost. JPG has no alpha channel at all, so any transparent area becomes solid white. If your image is a logo or a cut-out with a transparent background, convert it to PNG instead, or keep the WebP — WebP supports transparency and is far smaller than PNG.
Yes, completely. No account, no watermark, no daily limit and no resolution cap. Unlike the photo effects on velvetmade.app there is no credit system here at all — conversion, batch processing and downloading are all free.
No. The conversion happens in your browser using HTML5 canvas, so your files never leave your device — not the originals and not the results. Nothing is transmitted, stored or seen by anyone else, which makes it safe for client work and private documents.
Yes. Switch to batch mode at the top, drop in as many as you like — a folder of 50 is no problem — set one quality for all of them, and download the results as a single ZIP. Each file is converted in your browser, so a large batch is limited only by your own machine.
No — for the web, WebP is the better format and converting away from it makes your pages slower. Convert to JPG only when a file has to leave the web and open somewhere that cannot read WebP. If you are going the other way, convert JPG to WebP instead.
Need it smaller as well as more compatible? The image resizer will resize and compress in the same pass, and it writes WebP too if you are ever going the other way for a website. Still not sure why the file would not open in the first place? That one has a longer answer. And once your file opens where you need it, the photo effects are all free to play with.
